Fa poc he comprat un nou monitor, un BenQ FP222Wa, que funciona a 1680x1050 a 60Hz i 24bits de color. Tambè he hagut d'actualitzar la gràfica i he triat una Nvidia perque he llegit que tenen menys problemes: la Asus N7600GS Silent (agp).
No he acertat en les compres (pel que fa a Ubuntu). Ara no puc arrancar el sistemes Dapper i Edggy, que avans funcionaben perfectament. Al menys el nou Feisty sí que arranca, però ha costat de configurar el sistema gràfic.
He instal·lat el driver propietari de Nvidia (NVIDIA-Linux-x86-1.0-9755-pkg1.run) amb la automodificació del xorg.conf, pero no ha solucionat el tema. Encara pitjor: el refresc de pantalla que avans era quasi correcte:61Hz, ara el tinc a 50Hz (m'ofereix 50 i 54).
Després he modificat el xorg.comf, i afegint la meva resolució nativa a la Section Screen, he aconseguit que la acceptés (avans d'instal·lar el driver no era possible).
Aquest es el meu xorg.conf (amb la meva ressolució nativa):

En un intent anterior he cambiat els valors de -Section "Monitor"- substituint els valors
HorizSync 28.0 - 51.0
VertRefresh 43.0 - 60.0
per els valors de la web de BenQ
Frecuencia Horizontal (máx.) KHz 30 - 82
Frecuencia Vertical (máx.) Hz 50 - 76
es a dir: HorizSync 30 - 82
VertRefresh 50 - 76
deixant el damés igual.
El resultat va ser no poder entrar al sistema (al menys en mode gràfic). La única diferencia amb l'actual es que llavors no tenia el driver de Nvidia instal·lat ni tenia el sistema totalment actualitzat (sembla mentida, pero son 222 Mb d'actualització amb els pocs dies que porta el Hard 5). Encara vaig provar de borrar els valors deixant la seccio aixi:
Section "Monitor"
Identifier "Generic Monitor"
HorizSync
VertRefresh
Option "DPMS"
EndSection
El resultat va ser també de no poder entrar al sistema. Potser habia de borrar tota la secció titol incluit, pero les instruccions no solent ser massa detallades.
En fi, voldria no haber de reinstal·lar de nou. Com cambio el refresc de pantalla?
Salut
